Data Acquisition - Digital Potentiometers

Digital potentiometers, or digipots, are a type of programmable and electronically controlled components used in applications relating to data acquisition. The X9318WP8IZ is a non-volatile Digipot, meaning it can store a predetermined resistance level or tension, even after power has been removed and then reapplied. It is ideal for a range of industrial applications which require accurate resistance tuning and various levels of control over current flow.

What is a Digital Potentiometer?

A digital potentiometer, or digipot, is an electronic circuit comprised of two proportional resistors which can be used to control current flow and voltage levels in circuits. Usually, the elements are connected between two nodes, allowing the two resistors to interact. The resistance of both resistors can be adjusted using a digital or analog input voltage or a set of unique commands. Digipots are considered an integral part of the control and data acquisition chain in industry-grade applications as they can be used to set various control parameters with high accuracy, including voltage regulation, current control and power allocation.

X9318WP8IZ Features

The X9318WP8IZ is a serial-based non-volatile digital potentiometer designed for applications which require precision resistance control and reliable operation. This state-of-the-art integrated circuit contains an 8-bit register, an 8-bit D/A converter, an 8-bit DAC (digital-to-analog converter) and 28 address pins, as well as 64 memory registers (receptacles) for storing resistance values. It also includes an EEPROM which can be used to store and recall a user-defined resistance level, allowing the user to restore the initial settings in the event of a power failure or similar interruption.The X9318WP8IZ measures 3mm x 3.2mm and is operated with a supply voltage range of 2.7 to 5.5V. It is also capable of operating in temperatures ranging from -40°C to +85°C and has an adjustable output resistance ranging from 10Ω to 200KΩ.

X9318WP8IZ Applications

The X9318WP8IZ is ideal for applications which require precise, repeatable, and programmable control over current flow and voltage levels, such as power supplies and motor controls. The ability to store and recall a user-defined resistance level makes this IC particularly well-suited for industrial applications which require reliable operation, such as factory automation, robotics, amplifier and antenna tuning, and aerospace systems. Additionally, this IC can be used in analog-to-digital conversion systems to adjust the resulting output in order to achieve a desired level of accuracy.

X9318WP8IZ Working Principle

In order to control current flow or voltage levels, the X9318WP8IZ utilizes an 8-bit register and an 8-bit D/A converter. The D/A converter is responsible for controlling the resistance level of the two proportional resistors which make up the Digipot. The register stores a value that represents the desired resistance level, and this value is then passed to the D/A converter, which changes the resistance accordingly. This in turn allows the user to adjust the current flow or voltage levels in a circuit.

Conclusion

The X9318WP8IZ digital potentiometer is an ideal component for applications which require programmable and reliable control over current flow and voltage levels. It offers repeatable and precise control, as well as the ability to store and recall a user-defined resistance level, which makes it an ideal component for industrial applications such as factory automation, robotics, analog-to-digital conversion systems, amplifier and antenna tuning, and aerospace systems. By utilizing an 8-bit register and an 8-bit D/A converter, the X9318WP8IZ allows for accurate and adjustable resistance settings, enabling the user to adjust the current flow or voltage levels in a circuit in order to optimize performance.
